[Tlhaloso e akaretsang] Polyethylene ke polasetiki, e tsejoang ka karo-karolelano e phahameng ea sekhahla, ho feto-fetoha ha maemo le botsitso ba lik'hemik'hale. E loketse lits'ebetso tsa liphaephe tsa khatello le tse se nang khatello. Hangata liphaephe tsa HDPE li entsoe ka polyethylene 100 resin, e nang le boima ba 930-970 kg / m3, e ka bang makhetlo a 7 ho feta a tšepe.

Polyethylene ke polasetiki, e tsejoang ka karo-karolelano e phahameng ea sekhahla, ho feto-fetoha ha maemo le botsitso ba lik'hemik'hale. E loketse lits'ebetso tsa liphaephe tsa khatello le tse se nang khatello. Hangata liphaephe tsa HDPE li entsoe ka polyethylene 100 resin, e nang le boima ba 930-970 kg / m3, e ka bang makhetlo a 7 ho feta a tšepe. Liphaephe tse bobebe li bonolo ho tsamaisa le ho kenya. Polyethylene ha e amehe ke ts'ebetso ea electrochemical corrosion, 'me ho tloaelehile hore liphaephe li pepesetsoe letsoai, acid le alkali. Sebaka se boreleli sa tube ea polyethylene se ke ke sa senyeha, 'me ho ferekana ho tlaase, kahoo tube ea polasetiki ha e amehe habonolo ke ho hōla ha likokoana-hloko. Bokhoni ba ho hanela tšenyo ea kutu le ho phalla kamehla ho etsa hore litlhoko tsa tlhokomelo ea liphaephe tsa HDPe li be tlase haholo. Pipe ea polyethylene e ka etsoa ka resin e matlafalitsoeng, e khetholloang e le PE100-RC, 'me ea eketsoa ho fokotsa khōlo ea crack. Liphaephe tse hlahisoang li ka ba le nako e telele ea tšebeletso, 'me polyethylene e na le phaello ea moruo nakong ea bophelo ba morero.

Kaha joale ho netefalitsoe hore na ho tšoarella ha liphaephe tsa HDPe, moruo o bohlokoa haholo ha lipeipi tsa polyethylene li sebelisoa lits'ebetsong tsa meaho ea ho boloka metsi. Ha ho bapisoa le liphaephe tsa tšepe tsa ductile, molemo o totobetseng oa liphaephe tsa polyethylene ke hore li ka thibela ho tsoa. Ho na le mefuta e 'meli ea ho lutla ha lipeipi: ho lutla ha manonyeletso, ho lutla ho phatlohileng le ho lutla ha perforation, tseo ho leng bonolo ho li sebetsana.

Boholo baPipe ea HDPEe pakeng tsa 1600 mm le 3260 mm, mme liphaephe tse kholo tse teng hona joale 'marakeng li ka sebelisoa. Ntle le lits'ebetso tsa phepelo ea metsi a masepala, liphaephe tsa polasetiki tse bophara bo boholo tse entsoeng ka polyethylene le tsona li ka sebelisoa ho tlosa letsoai metsing a leoatle le litsing tsa kalafo ea metsi a litšila. Liphaephe tse kholo tsa bophara li ka tloha ho 315 cm ho isa ho 1200 cm. Bophara bo boholoPipe ea HDPee tšoarella haholo ebile e ka tšeptjoa. Ka mor'a ho patoa fatše, e ka sebetsa ka lilemo tse mashome 'me e hloka tlhokomelo e fokolang, kahoo e loketse haholo lits'ebetsong tsa ho hloekisa metsi a litšila. Ho tšoarella ha phala ea polyethylene ho eketseha ha boholo ba eona bo ntse bo eketseha, bo bonts'a ts'ebetso e makatsang ea anti-vibration. Nka tšisinyeho ea lefatše ea 1995 Kobe Japane e le mohlala, mehaho ea litoropo; lipeipi tse ling kaofela li hloleha bonyane hanngoe lik'hilomithara tse ling le tse ling tse 3, 'me tsamaiso eohle ea lipeipi tsa HDPE ha e na ho hlōleha.

Melemo ea phala ea HDPE: 1. Botsitso bo botle ba lik'hemik'hale: HDPE ha e na polarity, botsitso bo botle ba lik'hemik'hale, ha e tsoale algae le libaktheria, ha e na tekanyo, 'me ke sehlahisoa se sireletsang tikoloho. 2. Matla a khokahanyo e ntle: sebelisa socket fusion ea motlakase kapa butt joint thermal fusion, e nang le manonyeletso a seng makae mme ha ho na ho lutla. 3. Ho hanyetsa ho phalla ha metsi a tlaase: Bokaholimo bo ka hare baPipe ea HDPee boreleli, e na le coefficient e tlase ea ho hanyetsa le phallo e kholo. 4. Ho hanyetsa hantle mocheso o tlaase le brittleness: mocheso oa brittleness ke (-40), 'me mehato e khethehileng ea tšireletso ha e hlokehe bakeng sa kaho e tlaase ea mocheso. 5. Ho hanyetsa ka mokhoa o motle oa ho senya: Teko ea papiso ea ho hanyetsa ha abrasion ea liphaephe tsa polyethylene le liphaephe tsa tšepe li bontša hore ho hanyetsa abrasion ea liphaephe tsa polyethylene ke makhetlo a 4 a liphaephe tsa tšepe. 6. Ho thibela botsofali le bophelo bo bolelele ba tšebeletso: Pipe ea HDPE e ka bolokoa kapa ea sebelisoa ka ntle ka lilemo tse 50 ntle le ho senngoa ke mahlaseli a ultraviolet.
